Full featured, but disappointed

This plugin is full featured, I was so exiting to install it. After some minutes of testing, sorry to say so but it’s true. It’s disappointed. It promises lots of things but without clear instructions, it’s hard to make it works. Tracking Number, Gallery ID, Galleries per tag, User permissions. What are those things? Okay, perhaps I’m stupid, but this plugin should be more informative and user friendly.

On the demo link provided by this plugin (xparkmedia.com/image-store/demos/store), I can’t found any shopping cart button even how to add to cart. This is okay, It showed on my test site. But what about image download after purchase? I fail to make it work. Also the watermark, not working for me.

This plugin is for veterans who have good knowledge on ecommerce. It has many promising features, but I failed to make it works (download after purchase, watermark, etc).
